@rubencarneiro Thank you. Something to try out later.

@MrT10001 I searched but couldn't find it

I will mark this as "solved" though the "problem" wasn't a problem and didn't need to be solved. Sorry for the fuss.

@Luksus Oh nice. Looks like someone else picked it up. Mine is usually collecting dust and only use when I need to test on tablets. It's still in xenial though 😅
Good luck to the new porter. Hopefully we can get focal. I think one of the main issues is that Lenovo sucks at releasing kernel sources that their supposed to do 😄

@muskist That's nice to hear👍😀

Thanks for your answer.
